Subject: [PATCH] Ticket #3575: generate timestamps with nanosecond precision
 for touch

Sample fish/utime helper content:

if TZ=UTC touch -m -d "$FISH_TOUCHMTIME_W_NSEC" "/${FISH_FILENAME}" 2>/dev/null &&
   TZ=UTC touch -a -d "$FISH_TOUCHATIME_W_NSEC" "/${FISH_FILENAME}" 2>/dev/null; then
  echo "### 000"
else
  echo "### 500"
fi
